TOSY Robotics, a robotics and high-tech toys manufacturer based in Vietnam, on Wednesday unveiled a portable speaker that doubles as a dancing robot at the CES, with the help of singing sensation Justin Bieber.

The battery-powered mRobo allows users to upload about 500 songs into the device and the music will play through an integrated speaker, the company said in a statement.

When the music begins playing, mRobo, which can listen to its own music, will "groove through a series of pre-programmed dance moves to virtually any genre of music," according to the statement.

"mRobo is one of the most innovative and interactive entertainment devices ever introduced," said Ho Vinh Hoang, Founder and CEO of TOSY Robotics. "We're thrilled to be able to unveil mRobo Ultra Bass here at CES 2012 with the help of one of the world's most recognized stars, Justin Bieber."

The CES is the world's largest consumer technology tradeshow. This year the event is held from January 10-13 in Las Vegas.

According to a report from Engadget, the dancing robot is expected to retail for about US$200 when it launches during the fall of 2012.
